The digestive respiratory and cardiovascular system

Skeletal The Cardiovascular System The branches of science that will help you understand the body parts and functions are anatomy and physiology. Anatomy deals with the study of the human body the component parts, structure and position and physiology the study of how the body functions. Body Systems The body comprises a number of systems including the: Cardiovascular system, Digestive system, Endocrine system, Muscular system, Neurological system, Respiratory system and the Skeletal system.

Based in Ontario, Canada, Tremblay is an experienced journalist and blogger specializing in nutrition, fitness, lifestyle, health and biotechnology, as well as real estate, agriculture and clean tech. Your digestive tract converts complex carbs, like the starch in bread, into sugar, which you can use for energy.

Your circulatory and digestive systems do not directly convert food into energy, but they process and circulate nutrients so your cells can use them for fuel. Video of the Day Food and Energy The foods you eat supply carbohydrates, proteins or fats -- and many foods contain a mix of all three.

These three macronutrients serve as your main energy source.

Digestive System Physiology

Carbs and proteins each contain 4 calories per gram, while fat is higher in calories, at 9 per gram. Each type of macronutrient undergoes different processing in your body and has unique pathways your body uses to turn them into usable energy. The Preferred Source of Energy Your body -- especially your muscles -- prefers to run on carbs, and sugar is the sole source of energy for your brain.

After a meal, your digestive tract breaks carbohydrates down into simple sugars, like glucose.

From there, the glucose gets absorbed into your bloodstream, and your circulatory system distributes it throughout your body, allowing your tissues to take up the sugar to use for energy.

A Concentrated Energy Source Fat is the most efficient way to store excess energy since it has a higher energy density than proteins or carbs. Most of the fat in food is found in the form of triglycerides, which contain three fatty acids bound together with a glycerol backbone.

Your digestive tract breaks triglycerides down into individual fatty acids for absorption. Your digestive system breaks protein down into its individual components, called amino acids, and your cells and tissues use amino acids to make new cellular proteins.Sep 28,  · • Th e respiratory system carries oxygen to and removes carbon dioxide from the blood.

• Th e circulatory system transports dissolved gases and nutrients through the body.

Structures and functions of the human digestive system

• Th e digestive system breaks down food, absorbs nutrients, and eliminates solid waste. • Organ systems working TOPIC HOW DO SYSTEMS WORK TOGETHER IN THE. The circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein.

The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.

The Cardiovascular System. The branches of science that will help you understand the body parts and functions are anatomy and physiology. The cardiovascular and the respiratory system both work toward the same goal: getting oxygen to tissues and getting carbon dioxide out.

The respiratory system is involved in supplying oxygen to the blood and removing carbon srmvision.comd: Jun 17, HOME Free Essays How the digestive, cardiovascular and respiratory system are interrelate How the digestive, cardiovascular and respiratory system are interrelate Essay A.
